Categorical data (or variable) consists of names representing categories. For example, the gender (categories of male & female) of the people where you work or go to school; or the make of cars in the parking lot (categories of Ford, GM, Toyota, Mazda, KIA, etc) is categorical data. Numerical data (or variable) consists of numbers that represent counts or measurements. For example, the number of males & females where you work or go to school; or the number of the make of cars Ford, GM, Toyota, Mazda, KIA, etc is numerical data.

What is the difference between a categorical variable and numerical variable?
Basically categorical variable yield data in the categories e.g sex (male, female), modes of transport (Bus, railway, etc) and numerical variables yield data in numerical form e.g. age (0-100), number of accident on a certain highway (0,1,2,..).
What is the difference between a variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
What is the difference between a factor and a covariate for multinomial logistic reg?
It is just a factor or categorical variable. On the other hand for instance, If your age is continuous (rather than age brackets) then it would be a covariate. If your age is given as age-brackets, then it wont be covariate.
What is the difference between categorical data and numerical data?
categorical data is data that can be assigned to distinct non-overlapping categories. ex: What cell phone provider do you use? response: {Telus, Bell Aliant, Telus, Bell Aliant, Rogers,Rogers,Koodo, Rogers, Telus Rogers}. The responses to question one fit into four categories numerical data set is when the data is compromised of numbers, specifically different amounts of money. ex: What was your cell phone bill for the previous month? response:{$27.50, $33.50, $45.70, $32.00, $54.90, $29.00, $43.65, $67.40, $35.89, $$39.67}.
What is the difference between a variable and a control?
a control is a object that cant be changed in an experiment and a variable is a object that can be changed in a expirament
What is the difference between a categorical variable and numerical variable?

What is one difference between a variable and a numerical expression?
The variable.
What is one difference between a variable expression and a numerical expression?
The variable.
What is the difference between continuous and categorical independent variables?
A categorical variable (also known as a discrete variable) is one whose range is countable; e.g. the variable answ has values [yes, no, not sure]. answ is a categorical variable with range 3.A continuous variable is one which is not categorical; e.g. weight is a continuous variable which can take any value between 0 and 1000 kg (say) for a human being.
Difference between dummy and categorical variable?
A dummy variable assumes a value of either 0 or 1. A categorical variable assumes one of a usually small number of values. For example, a categorical variable might assume the values 'F' or 'M' for female or male.
What is the difference between a numerical expression and a variable expression?
A variable expression includes variables.
What is the difference between a coefficient and variable?
A variable is a part of a term which can change. A coefficient is a numerical constant, associated with a variable. For example, in the term 3x^2 , 3 is the coefficient, while x is a variable.
The difference between fixed and variable inputs?
difference between fixed and variable inputs
What is the difference between a numerical expression and a algebraic expression?
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
What is difference between continuous and ordinal variable?
A continuous variable is one which can take any numerical value over some interval. An ordinal variable is one that can take non-numerical or categoric values which can be put into some logical order but where the difference between successive categories cannot be quantified. One example may be Small-Medium-Large, or a popular one among opinion pollsters: Disagree Strongly-Disagree-Agree-Agree Strongly.
What is the difference between numerical and non-numerical data?
Numerical data is numbers. Non-numerical data is anything else.
Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
